I COLUMN-MOLD.

Specification of Letters Patent.

Patented Dec. 4, 191W.

Application filed February 24, 1917. Serial No. 150,699.

To all whom it may concern:

Be it known that 1, Louis H. MEISTER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Column-Molds, of which the following is a specification.

This invention relates to molds for forming cOluInns and posts of concrete or analogous material, and its object is to provide a novel and improved mold which is in sections so that adjustments may be made to adapt the mold for columns of different dimensions.

The invention also has for its object to provide a novel and improved meansfor connecting and fastening the mold sections together.

With the objects stated in view, the invention consists in a combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawings forming a part of this specification.

In the drawings,

Figure 1 is an elevation of the mold, partly broken away;

Fig. 2 is a vertical section thereof;

Fig. 3 is an enlarged elevation of a frag ment of the mold, with parts broken away and in section;

Figs. 4, 5 and 6 are-enlarged sectional details on the lines 44, 5-5 and 66, re spectively, of Fig. 1;

Fig. 7 is a detail in perspective;

Fig. 8 is an enlarged elevation of a detail, and

Fig. 9 is a section on the line 99 of Fig. 8.

Referring specifically to the drawings, the mold is made up of three sections denoted, respectively, by the reference characters 10, 11 and 12. The section 10 is at the top and is flared upwardly. The section 11 is the and 12 of the mold are each made up of two or more units according to the diameter of the column to be molded, the curvature of the units of course being such that when they are assembled they form a true circle. For columns of other cross-sections, the mold wall units will be shaped accordingly. The

drawings show the sections 11 and 12 made up of two units.

The section 11 is telescoped upwardly into the bottom of the section 10, the latter being made in one piece and in several sizes, and having its bottom edge reinforced by an external ring 13, brazed or otherwise fastened thereon, to keep the bottom edge stiff, to preserve the circular form of the section, and to prevent denting of its bottom edge. The ring is divided at one or more places, the ends being turned outward as shown at 14. Between the ends 14, the bottom edge of the section 10 has a deep notch 16.

The ends of the units of which the section 11 is made up are formed with outstanding flanges 17 which lap and have at their extremities lateral bends 18 at right angles thereto. The notch or notches 16 of the section 10 receive the upper ends of the parts 17 when said section and the section 11 are joined. At the top, the lapping flanges 17 have a vertical slot 19 through which a bolt 20 passes, said bolt also passing through the parts 14, as shown in Fig. 4, and thus serving to fasten the sections 10 and 11 together.

The section 12 has its units meet edge to edge or in abutting relation, as shown in Fig. 6, and to said edge portions are fastened angle bars 21 to reinforce the same, the outstanding flanges of the angle bars lapping and being bolted together as shown at 22.

In order to applythe section 12 to the section 11 externally and from the bottom, the units of the section 12 are firstspread slightly before the bolts'22 are applied to permit the parts 17 of the section 11 to come between the outstanding flanges of the angle bars 21, as shown in Fig. 5, with the parts 18 clear of the same. The parts 17, as well as the outstanding flanges of the angle bars 21, will be apertured, as shown at 23 and 24,

for the reception of certain ones of the bolts places by bolts 25 drawn tight by wedges 25 Plain bolts may be used but wedges are preferable as they can be quickly applied and afford a better clamping action. Below the bottom of the section 11, it Will appear that the outstanding flanges of the angle bars 21 would be slightly spaced on Figs. Sand 9 show the ring applied to the portion of the mold where the section line 5.5 in Fig. 1 appears, although the ring is not shown in Fig. 1. The ring will. also be placed lower down around the section 12 as shown in Fig. 1. i In order that the ring may fit the wall of the mold over the angle bars 21, its web 27 is recessed as shown at 28, and its base 26 is also recessed as shown at 2%. Two plates 30 are then riveted as shown at 31 to the ends of the ring on the upper face of the web 27, these plates being located on opposite sides of the parts 17 and the outstanding flanges of the angle bars 21, their inner edges being recessed, as shown at32, to clear the parts 1S. Overand under the outer portions of the plates 30 are placed two flat bars 33 and 34, these being loosely bolted at 35 and 36 to the respective plates. The bolts 35 and 36 serve to secure the bars 33 and 34 to the plates 30, and the bolt 33 passes through registering slots 37 in the two plates. In the outer end of the slots 37 is inserted a wedge 38 which latter, acting on the outer edge of the adjacent plate 30, serves to draw the two plates toward each other, and thereby contract the ring 2-6 about the mold. 7

"By the structure hereinbefore described, the several sections of the mold can be easily and quickly assembledor separated, and the sections are securely fastened together. The vertical butt joint between the units forming the sections 11 and 12 enables a column to be molded which is perfectly smooth on the outside. The angle bars 21 seat slidably behind the parts 18, their outstanding flanges abutting against the inner surface .of

said parts 18, this arrangement serving to assist in retaining the mold 1n lineal rigidity so that the profile of the column will be a straight line.

I claim 1. A mold comprising an encircling Wall composed of alined sections one of which extends telescopically at one end into the other section, the last-mentioned section having edge notches where the other section enters the same, a ring encircling said last-mentioned section at the notched edge. said ring being divided at the notches and having outturned ends, the other section being composed of separate units having outstainling flanges at their ends which lap, said flanges at the telescoping part of the section seating in the aforesaid notches and between the aforesaid outturned end portions of the ring, and fasteners passing through said end portions of the ring and the flanges seating therebetween.

2. A mold comprising an encircling wall composed of alined sections one of which extends telescopically over the other section. each of said sections being composed of separate units, the units of one section having outstanding lapping flanges at their ends, angle barsfaslened to the ends of the units of the other section and having their outstanding flanges lappin fasteners passing through the last-mentioned flanges, the firstmentioned flanges at the telescoping portions of the sections seating between the lastmentioned flanges, and fasteners passing through the last-mentioned portions of the flanges.

3. A mold comprising an encircling wall composed of alined sections one of which extends telescopically over the other section, each of said sect-ions being composed of separate units, the units of one section having outstanding flanges lapping at their ends, said flanges having lateral bends in opposite directions at their extremities, angle bars fastened to the ends of the units of the other section and having their outslanding flanges lapping and abutting at their extremities against the aforesaid lateral .bends, fasteners passing through the lustmentioned flanges, the first-mentioned flanges at the telescoping portions of the sections seating between the last-mentioned flanges, and fasteners passing through the last-mentioned portions of the flanges.

In testimony whereof I allix my signature.

LOUIS H. MEISTER.
